摘要
在介绍生态足迹的概念和计算方法的基础上,以山东省昌乐县2003年统计年鉴数据为依据,计算和分析了生态足迹。结果表明,昌乐县人均生态足迹为1.1099hm2,而昌乐县人均生态承载力为0.5422hm2,可利用的人均生态承载力为0.4771hm2,人均生态足迹赤字为0.6328hm2。昌乐县的人均生态足迹赤字是人均生态承载力的1.2倍,在目前的社会经济发展过程中,昌乐县人口对自然资源的利用逐年的增加,区域生态系统已经处于人类的过度开发利用和压力状态之下。
According to the data of the 2003s' statistical yearbook of Changle County,Shandong Province,the authors calculate and analyze the ecological footprints based on the introduction to the concept and calculation method of ecological footprint indicator.The results indicated that the ecological footprint and ecological deficit per capita of Changle County in 2003 were 1.109967hm^2 and 0.632847hm^2 respectively.The ecological footprint deficit shows that the human load has already stayed beyond the regional bio-capacity and the regional natural ecosystem is under great pressure of human activities.
